all vertical sections on the same line, 3 3 of Fig. 1, the two last being enlarged and showing parts-only of the structure.

A post or standard 1 is set in a suitable` foundation below the surface of the floor that lies adjacent to the turn-table, anda plate 2 on top of the standard carries a ball race 3 that can be adjusted with reference to the horizontal plane. The drawings show a standard that is comprised of three vertical equidistant wings (Fig. 2), and a triangular top plate 1L (Fig. 1). The ball race 3 is shown as an extension of a triangular plate 3a, which in size corresponds with the top piece 1a of the standard. The plate 3a of the ball race is adjusted by means of three jack screws 4 that are threaded into the plate 3a,

at the angles, respectively, and bearl against the top piece 1a of the standard. When the ball race has been adjusted properly, it isset or locked in position by 'cap bolts that are contained within the screws 4, respectively, and are tapped into the top 1a of the standard. By tightening the bolt the parts areV locked. The bore of the jack screws that contains the bolts is enlarged at the upper and lower ends of the screws, as shown in Fig. 4, to allow for the tilting of the ball race. Finally, the. rotatable frame is adjustable with reference to the ball race. The rotatable frame in the construction shown comprises two parallel channel beams, 6, 6, that carry rollers 7 at their outer ends, and are rigidly connected by a cross beam 8. The rollers 7 are adapted to support the ends of the frame upon theloor when the frame is depressed by the weight of an automobile that isbeing wheeled upon it.4 The ball bearings 9 are placed between the race 3 and the cap 10 (F ig.3) and the frame is adjusted with reference to the cap by means of jack screws 11 and locked in place by cap screws'12.- The cross beam is tapped for the jack screws 11 which extend through it and bear against the cap 10, and the cap screws 12 extend through the beam 8 and are tapped into the cap 10. A flange 10a protects the bearing. f

As indicated in the drawings, the pit for the turn-table need only be suiiiciently wide and deep to contain the bearings and enable the cross beam 8 to turn around, and ,obviously the width of the pit may be lessened by using in place 'of the channel beam 8 one that is not as wide.

If the Hoor kadjacent to the turn-table is not level, which as a rule Will prove to be the case, the turn-table can readily be adjusted to it by means of the adjusting jack screws 4, in the manner described. Inasmuch as this adjustment inclines the ball race, the beams 6 and 8 can be placed so that they lie in the plane of the floor, and will'revolve in 1t. Thus` an automobile may readily enter the table from any point on the circu1n- .ference of the turn-table.

What I claim is 1. In a turn-table, the combination with a suitable standard, of separate bearings for the revoluble frame; adjustable means for attaching the bearings to the standard with reference to the level of the adjacent floor; and a suitable frame revoluble upon said bearings; scribed.

2. In a turn-table, the combination with a suitable standard, of separate bearings for the revoluble frame; -adjustable means for attaching the bearings to the standard with reference to the level-of the adjacent floor a suitable frame revoluble upon said bearings; and means for locking the bearings to the standard when adjusted; substantially as shown and described.

3. In a turn-table, the combination with a suitable standard having bearings for the revoluble frame, of a cap revoluble thereon; a suitable frame carried by the cap; and means for adjusting the frame with reference to said cap; substantially as shown and described.

4. In a turn-table, the combination with substantially as shown and dea suitable standard, having bearings for the revoluble frame, of a cap revoluble thereon;

a suitable frame carried by the cap; means 5. In a tuin-table, the combination with a suitable standard, of separate bearings for the revoluble frame; adjustable means for attaching the bearings to the standard with ing the frame in positionfsubstantially as ,a

shown and described.`

7 In a turn-table, the ycombination with a suitable standard, of a plate with bearings; a revolubl'e frame upon said bearings; jack screws tapped in said plate and engagingsaid gg,

standard; and cap-bolts contained in said screws and tapped in said standard for-locking the plate 1n position; substantially as shown and described.`
